State-owned electricity utility Eskom says it is “not feasible” for the National Energy Regulator of South Africa (Nersa) to make a revenue determination, for implementation on April 1 2022, on the basis of a new methodology that has yet to be consulted or finalised. On September 24, Nersa published a consultation paper on a possible new price determination methodology in which it states that the “current revenue-based methodology has fallen short in providing stable prices”.
